Calibrachoa plant named ‘Suncalwine’

ABSTRACT

A new and distinct cultivar of  Calibrachoa  plant named ‘Suncalwine’, characterized by its compact, upright, outwardly spreading and mounding plant habit; vigorous growth habit; freely branching and flowering plant habit; early and long flowering period; numerous single purple-colored flowers with darker purple-colored venation; and good garden performance.

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘SUNCALWINE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa sp. and hereinafter referred to by the name ‘Suncalwine’.

The new Calibrachoa plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to develop new compact, mounding and freely branching Calibrachoa plants with attractive and uniquely colored flowers.

The new Calibrachoa plant is a naturally-occurring branch mutation of a proprietary selection of Calibrachoa sp. identified as code number 2572-2, not patented. The new Calibrachoa plant was discovered and selected by the Inventor on a single flowering plant within a population of plants of the mutation parent selection in a controlled greenhouse environment in Higashiomi, Shiga, Japan in September, 2008.

Asexual reproduction of the new Calibrachoa plant by vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since September, 2008 has shown that the unique features of this new Calibrachoa plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Calibrachoa have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Suncalwine’. These characteristics in combination distinguish ‘Suncalwine’ as a new and distinct Calibrachoa plant:

-   -   1. Compact, upright, outwardly spreading and mounding plant         habit.     -   2. Vigorous growth habit.     -   3. Freely branching and flowering plant habit.     -   4. Early and long flowering period.     -   5. Numerous single purple-colored flowers with darker         purple-colored venation.     -   6. Good garden performance.

Plants of the new Calibrachoa can be compared to plants of the mutation parent selection. Plants of the new Calibrachoa differ primarily from plants of the mutation parent selection primarily in flower color as plants of the mutation parent selection have red purple-colored flowers.

Plants of the new Calibrachoa can also be compared to plants of Calibrachoa ‘Sunbelao’, disclosed in U.S. Plant Pat. No. 22,391. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Calibrachoa and ‘Sunbelao’ differed primarily in the following characteristics:

-   -   1. Plants of the new Calibrachoa had smaller leaves than plants         of ‘Sunbelao’.     -   2. Plants of the new Calibrachoa had smaller flowers than plants         of ‘Sunbelao’.     -   3. Plants of the new Calibrachoa and ‘Sunbelao’ differ in petal         lobe shape.     -   4. Plants of the new Calibrachoa and ‘Sunbelao’ differed in         flower color as plants of ‘Sunbelao’ had purple violet-colored         flowers with dark purple-colored venation.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Calibrachoa plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Calibrachoa plant.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Suncalwine’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Suncalwine’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 15-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial Calibrachoa production. During the production of the plants, day temperatures averaged 23° C. and night temperatures averaged 13° C. Plants were four months old when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
